Meshgrid

This is a very simple function to find the local maximum in any dimensional array. As simple as it is it still gives nice results.I use the imdilate() function as a maximum operation and then compare the data to the result.The function receives three parameters:the data, a vector defining the...

STREAMCOLOR(X,Y,U,V,STARTX,STARTY,VMAG) or STREAMCOLOR(X,Y,Z,U,V,W,STARTX,STARTY,STARTZ,VMAG) creates streamlines from 2D or 3D vector data U,V,W. The arrays X,Y,Z define the coordinates for U,V,W and must be monotonic and 3D plaid (as if produced by MESHGRID). STARTX, STARTY, and STARTZ define...

Takes in a point cloud in xyz format, and then converts that into a MATLAB-style grid with a latitude vector, longitude vector, glat/glon grid (made using meshgrid), and a z (altitude) matrix. It then saves these into a specified output .mat file.

Converts a regular mesh defined by X,Y and Z into a regular triangulation. The output is patch data (triangles) in the faces d-deDUFd-deDt and vertices d-deDUVd-deDt format. The quadrilateral mesh faces are converted to triangles by splitting the faces into triangles according to the setting...

This program performs arithmatic operations +, -, * and / on an image voxel by voxel. It takes in offset to let users select the region toiterate. It is useful for image analysis and processing when more control is needed than using Matlab meshgrid function. This is a part of InSPIREsoftware...

This m file constructs the meshgrid needed to rended the classic Klein bottle. It takes a variable parameter list: the longitudinal resolution, the rotational resolution, the size of the "handle loop", the size of the base and the height of the body.

JSURF is similar in almost all respects to the standard SURF plot except that it admits a second matrix T of z-coordinates of size [m,n] that is used to plot over the base surface described by coordinates (x,y,z). JSURF(x,y,z,T) plots the 3D surface T onto the surface described by (x,y,z)....

This program represents a further development of the standard powerful d-deDUnlinfitd-deDt facility already in matlab. The major problem with d-deDUnlinfitd-deDt is that it can only handle fitting of one dimensional arrays (x, y) where x is the independent variable and y is the dependent one.The...

Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides...

This function generates patch data (faces d-deDUFd-deDt, vertices d-deDUVd-deDt and color data d-deDUCd-deDt) for 3D images. The patches are only generated for the voxels specified by the linear indices in d-deDUINDd-deDt. The variable d-deDUptyped-deDt indicatesthe type of patch:d-de?vd-deOao...

The code is probably not very efficient, as it contains a for loop. Any improvement ideas are welcomed.example:ParameterMatrix=abs(meshgrid(0:199)-100) / 20;inputimg = double(checkerboard(10,10,10)>0.5);blurred=VariableBlur(inputimg, ParameterMatrix);imagesc(blurred);colormap(gray);

STLWRITE(FILE,fv) writes a stereolithography (STL) file to FILE for a triangulated patch defined by FV (a structure with fields 'vertices' and 'faces'). STLWRITE(FILE,FACES,VERTICES) takes faces and vertices separately, rather than in an FV struct STLWRITE(FILE,X,Y,Z) creates an STL file from...
